Hello allI currently run Version 5.11.2 (@65536ba7a376 202503180650) and we have observed extreme peaks in CPU load and memory use. After a large number of twekas (I have posted them here before) the problem persists with Sogo now triggering the oomkiller. In the past we had found through SQL queries that the extreme peak in memory use was caused by a calendar which somehow had managed to have re-ocurring events going back to the 17th century, we guessed it must have been an error in a user entry.
Now I have kept the logs and investigated what the last queries were that happened before the peaks, but they did not appear to trigger anything unexpected.
I wonder what I could do to find the cause of these peaks. It appears to run at very good performance throughout, but then, approximately once every one or two days something triggers a peak that causes a complete meltdown.
Do any of you have suggestions on what to do? Greetings; -- Daniel Kollmer Computer Technology Group NIKHEF - Dutch National Institute for Sub-atomic Physics
