PyCMDS crashing with long scans #71

Closed jhandali closed 7 years ago

jhandali commented 8 years ago

PyCMDS crashes when doing long (multidimensional, I haven't yet tried to do very very long 1d scans) scans. The program does not technically crash but just decides at one point in the scan to stop moving. No error reported. In the instances that I have seen, the freezing occurred in the middle of a slice and not during a carriage return. I have twice seen the program freeze around 50 minutes into the scan, and once 14 minutes into the scan. In both cases, OPA1 motors were the scanning motors.

It's basically impossible to do any serious scanning. I'm checking to see if the same thing occurs when OPA2 or the TOPAS is the scanning OPA.

Gosh, that sounds terrible... I don't really have the information or time to diagnose this right now. Please keep me tuned.

jhandali commented 8 years ago

Ya, will do. I've done some tests and can tell you more tomorrow. We can address it when you are available.

I think that I've fixed this. I've managed to do a full 51x51 2D frequency scan (with spectral delay correction) without issue. Try it out and let me know if you experience any further problems.

I'm not sure if what I've done has negatively affected scan speed - let me know about that.

@jhandali Is this issue still relevant?

ksunden commented 7 years ago

I have not heard anything on this issue lately, and long scans have been run on both systems. Closing
