Hi @msrutek-paylocity It looks like this is coming from the same place, which is related to memory management. We are working on a fix in our next HF, will update you when it's out.

MikePendo commented 1 month ago

@msrutek-paylocity We just released new version 3.4.3, we had fixed significant memory issue that might arise on bad network. That might trigger or be the cause for the memory issue you have, any chance you could fetch the latest release and see and track the strange crashes once again. My comment applies to almost all issues you have found that related to memory, so I will copy paste that messages to the the relevant threads

Hi @MikePendo , let us update and gather the results in the coming weeks/months!

TehilaTaub commented 2 weeks ago

Hi @msrutek-paylocity, Please upgrade to 3.4.3 and if you notice similar issues, please open a new ticket with the crash logs. Closing this one now.
