Description dpkesling 2021-08-18 18:04:11 UTC
Description:
When I use ExitLibreOffice command on pulldown, the user interface window closes properly, but continuing background processes consume all available memory... as observed using Microsoft Resource Monitor. Sometimes, after a couple minutes, the machine will eventually succeed in closing down all Libre processes... other times the machine hard freezes, not accepting any input.

Steps to Reproduce:
1.Calc session w/ 8 column x 8000 row table. 2 hour session occasionally deleting single row at a time.
2.Use pulldown to ExitLibreOffice command.
3. (Look at software environment described below)

Actual Results:
Interface window closes promptly without issue. Problem is in post-processing stage. As observed on Resource Monitor graphs, memory usage spikes about 7GB indicated before machine freezes. Neither CPU nor Disk usage are particularly heavy. It's memory contention/exhaustion.

Expected Results:
Postclose processing does not consume all available memory, freezing the machine.


Reproducible: Always


User Profile Reset: Yes

Running on an HP 8530 with 8GB installed memory, 740 GB available disk space.

I may have discovered what is happening. I work with an .ods file during work session, but need to save a copy as a .csv for post-processing in a Python routine and R. What I have been doing is simply doing a SELECT ALL then COPY of the .ods, then open the .csv file, SELECT ALL, DELETE, then PASTE.
This is the end of my session after performing this action, so I immediately ExitLibre.
Tonight, I tried simply doing a SAVE AS of the .ods to the .csv file. On close down, I noticed NO memory hit due to soffice.
I suggest that Calc doesn't deal well with large objects in its clipboard at shutdown and really struggles to release that allocated memory. A guess though.

Could you please retest your problem from Description in latest LibreOffice 7.2.7 or 7.3.3?
