Accidental double post. Please delete
VxWorks 6.9.4.1 only supports NFSv3 over UDP. NetApp appliances are only optimized for NFSv3 over TCP. A single VME doing a multidimensional scan is sufficient to overwhelm the single task handling UDP running in the "Legacy Domain" on the NetApp appliance.
Good periods where there are no problems saving data alternate with bad periods where every attempt to save data is abandoned. The call that fails during the bad periods is fseek in writeXDR_setpos in writeXDR.c:
Line 157 in 8f83286
The call to fseek fails, returning -1. errno is 3080197 (in decimal) and strerror(errno) is S_rpcLib_RPC_TIMEDOUT
scanProg.st uses the "%T" format for strftime, which is not implemented in Visual Studio 2010. This results in the IOC crashing when a scan is executed.
Here is some info about the problem:
http://ebanshi.cc/questions/4828844/debug-assertion-failure-while-using-strftime
Replacing "%T" with "%H:%M:%S" should fix the problem.
I'm using the following:
Windows 7 (64-bit)

If I crate a branch on forked repo and try to checkout the branch afterwards I get these error messages:
error: Your local changes to the following files would be overwritten by checkout:

Please, commit your changes or stash them before you can switch branches.

It turns out that the line endings want to be different on my Linux system.
warning: CRLF will be replaced by LF in sscanApp/Db/scanProgress.db.
The file will have its original line endings in your working directory.
warning: CRLF will be replaced by LF in sscanApp/src/scanProg.st.

It does not happen with any other epics-modules/.
Would maintainer consider fixing the two files in question?

This thread on techtalk made me think it was probably to do with not getting somthing from the build of the sequencer support module. I have checked that the build succeeded for seq, and done a make clean uninstall before typing make to ensure that any changes to configure/RELEASE were picked up.
Any ideas? let me know if I can provide any more information to help diagnose the problem

Hello all,
Recently, we've had a sscan record fail to execute complaining about the positioner limits (i.e., P0_ Value < LO_LIMIT @ point0). After some debugging, we have realized that the problem was on how LO_LIMIT and HI_LIMITs were determined for motors.
Particularly, from what I understand (and I could very well be wrong), if DHLM == DLLM == 0, the software limits are disabled (in the motor record) and the motor can move as long as it is within the hardware limits. The problem arises if we use the user fields as our positioner (VAL and RBV), because HLM = DHLM + OFF (or DLLM + OFF if DIR=-1) and LLM = DLLM + OFF (or DHLM + OFF for DIR=-1). But since the sscan record uses the upper_dist_limit/lower_dist_limit, which are obtained here, these limits are not read as 0 and the check fails (this check in particular).
We have worked around the issue by setting DHLM (and DLLM) to a very large range (-9999 and 9999), so that this is never triggered. But I wonder if there is a way we could improve upon it. The first question is if we could forego the check altogether, so that the positioner PV itself would limit the range. Alternatively, the check could be changed to be if (pPos>p_lr != pPos>p_hr), although in this case, it is possible someone has set the limits to the same location to block the motor into a fixed position (nevertheless, the positioner PV would still block itself from being set outside the desired limits). Finally, the message could remain the same, but the error be changed into a warning, so the scan would still run, but the user could be alerted of the "misconfiguration" (?).
My main concern is that if this check was to be changed, the current functionality would also be changed, so an upgrade could cause major issues (for IOCs relying on the current behavior). But I wanted to open up the discussion in case others also encountered the same issue.
Warnings while compiling the code
Steps to reproduce
Expected behaviour
No warnings
Actual behaviour
The compilation reports warnings about potential string truncation and overflow. One formatting warning was reported too.

saveData_writeXDR.c's proc_file_subdir function appends a directory separator, "/", before checking for the existence of the specified subdirectory:
https://github.com/epics-modules/sscan/blob/master/sscanApp/src/saveData_writeXDR.c#L3625
This is a problem because stat() returns -1 on Windows if the path has a trailing directory separator.
This is confusing for users because when they choose a valid directory for $(P)saveData_fileSystem, $(P)saveData_message is "saveData OK", but when they choose a valid directory for $(P)saveData_subDir, $(P)saveData_message is "Invalid directory !!!". If they choose a subdirectory that doesn't exist, saveData successfully creates it and then fails to detect that the directory exists. This is the debug message that gets printed when the subdirectory PV is updated:
epics> var debug_saveData 10
epics> saveDataTask: MSG_FILE_SUBDIR, val=12
saveData: stat returned -1 for filename 'C:/data/mda/2016/12/'; errno=2
areaDetector handles this by stripping the trailing directory separator before testing for the existence of the directory:
https://github.com/areaDetector/ADCore/blob/master/ADApp/ADSrc/asynNDArrayDriver.cpp#L77
There are many ways to fix this in saveData_writeXDR.c (appending the separator in proc_file_subdir after calling fileStatus, stripping a trailing separator in fileStatus before calling stat), but it isn't obvious which approach is best.
Has anyone else noticed that the CPT field sometimes is not posted, and posted in bunch of two?
I do think that it is incremented correctly it is just that it is posted irregularly, and to the user it looks like it might take two data points one some steps, and zero on some.
Example monitoring the CPT field and FAZE field, note that I run the positioner very slow so there several seconds when the positioner is moving. The following example are camonitors of what happens at each step. This is continuous sequence were the motors moves for several seconds when I comment.

It seems like it it sometimes misses to post CPT and then post it two times.
