System messages will indicate warnings/errors with wording like the following: wdsysmon: %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: %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: <CmdBold>show process<noCmdBold> <CmdArg><job_id><noCmdArg> <CmdBold>details location<noCmdBold> <CmdArg><R/S/I><noCmdArg> <job_id> is job id for lda_server on the failing node. <R/S/I> 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.
