Symptom: Card will crash and reload itself. The crash info file will be collected at LCP core: directory *************************** Line 65209: 134497: Jun 13 05:15:54.894 BST: %SAMI-3-SAMI_SYSLOG_ERR: SAMI 2/0: %SAMI-3-730205: SAMI User Space: ERROR: Rcvd HM Datapath 2 failure event from 8/1. <---(Proc8/Proc1) : //70 more occurrences of this log// : Line 65778: 134713: Jun 13 05:19:49.883 BST: %SAMI-3-SAMI_SYSLOG_ERR: SAMI 2/0: %SAMI-3-730205: SAMI User Space: ERROR: Rcvd HM Datapath 2 failure event from 4/1. <---(Proc4/Proc1) Conditions: Different packet type takes different processing time in the Lookup leading to packet reaching late to Resequencer ME. Incase if the specific seq number packet does reach to resequencer before its buffers filled up completely, it can cause the resequencer's threads to hung leading to WSG crash due to HM failure. Resequencer ME is not robust enough to handle such situations.
