- Parallels Dispatcher Service process,
prl_disp_service, consumes a lot of memory (RSS up to several GBs).
- Parallels Cloud Server 6.0 Update 5 is installed on the server.
The issue is recognized as a product bug with internal ID PSBM-24926: a memory leak in
Issue is permanently fixed in code starting from PCS 6.0 Update 6. Install pending updates to address the issue.
If for some reason installing updates is not an option, temporary solution is to kill the Dispatcher service:
# kill -9 `pidof prl_disp_service`
NOTE: Make sure you use '-9' (SIGKILL) signal, as other signals will cause the Virtual Environments to be stopped/suspended, causing the downtime for the services.
Please also note that memory allocation for Dispatcher process(VSZ) can be several GBs, it is expected behavior.
