Description (partial)

Symptom:
sysdb and GSP syslog messages such as the following are observed:

gsp[255]: %OS-gsp-3-MSG_ENQUEUE_ISSUE : Process pkg/bin/icpe_satmgr (pid 561490) not picking up messages, 1 msgs dropped. 10001 msgs pending, taking 7319208 bytes
sysdb_svr_admin[450]: %SYSDB-SYSDB-6-TIMEOUT_EDM : EDM request for 'admin/oper/inventory/rack/0/entity/131/entity/0/attrib/inv_basic_bag' from 'ntpdc' (jid 218, node 0/1/CPU0). No response from 'invmgr' (jid 268, node 0/RP0/CPU0) within the timeout period (100 seconds)

  445    209001   6        sysdb_mc  Send   13:57:35:0673  561490  icpe_satmgr
 1192    561490   1     icpe_satmgr  Send   13:57:38:0790  209001  sysdb_mc

Conditions:
Only hit with nV satellite configuration.

Issue is only hit via polling operational information such as "show interfaces" and "show nv satellite status" concurrently and at a high rate via both SNMP and the CLI over a period of many hours.

It is difficult to hit the problem condition as it is due to an unusual timing condition.
