Symptom

Process lda_server may be terminated by wdsysmon due to cirtical limit of more than 950 file handles used. System messages will indicate warnings/errors with wording like the following: wdsysmon[384]: %HA-HA_WD-4-FD_MAJ_LIM : Process lda_server, pid 53281 is using 900 file descriptors out of a max of 1000. Major limit (90%) crossed. wdsysmon[384]: %HA-HA_WD-3-FD_CRIT_LIM : Process lda_server, pid 53281 is using 950 file descriptors out of a max of 1000. Critical limit (95%) crossed. The show processes file command will show a high number of connection to sysdb_svr_local: show process details location is job id for lda_server on the failing node. is the Rack/Slot/Instance location of the failing node.

Conditions

This defect may occurs under very rare condition, such as: a) 900+ changes of hw-mdoule breakout configuration. b) Defects that will cause interface HW to fail persistently, which in turn will cause the system to retry HW initialization a large number of times.

Workaround

The system recovers from the fail state on its own, without service impact following the forced lda_server termination and restart. In the case of condition b) above, the issue causing the interface HW initialization failure need to be resolved as a separate issue.
