Title: cmk-update-agent: Retry locking
Component: agents
Level: 1
Class: Bug fix
Version: 2.2.0i1
The agent updater is designed to have no more than one instance running
at a time on a host. This is implemented by holding a file lock while running.
We recently observed that a lock may sometimes fail briefly after it was
released by a previous agent updater instance, possibly due to some anti virus
software.
To mitigate this situation, the locking is now retried 10 times before aborting
the agent updater call.
