Summary0005943: Excessive memory usage when creating a recurring event
Description

When creating a recurring event (for example, every day for a year), excessively high memory utilization occurs (often gigabytes when processing one event).
Example from logs:

With each new repeating event on the same day, memory consumption increases exponentially.

Presumably, memory consumption occurs when processing a response to a query to the database.

''SELECT b.c_content,a.c_partmails,a.c_partstates,a.c_isopaque,a.c_status,a.c_cycleinfo,a.c_orgmail,b.c_name,a.c_uid,a.c_startdate,a.c_enddate,a.c_isallday FROM sogo_quick_appointment a, sogo_store b WHERE (a.c_folder_id = 6 AND b.c_folder_id = 6) AND ((c_component = 'vevent') AND ((c_startdate IS NULL) OR (c_startdate <= 1742280851)) AND ((c_cycleenddate IS NULL) OR (c_cycleenddate >= 1710743653)) AND (c_iscycle = 1)) AND a.c_name = b.c_name AND (c_deleted != 1 OR c_deleted IS NULL)''

Increasing the memory limit for workers (SxVMemLimit) does not solve the problem.

Steps To Reproduce
  • Create a recurring event with 3-5 recipients on one SOGo server.
  • Add 4-6 more similar events on the same days, but with different times (intersection in time is not necessary). An event validity period of 1 year is sufficient.
  • After creating 5-6 (or more) repeating events, SOGo WatchDog kills the process due to high memory utilization.
