EAM module was coring with segmentation fault on malloc failure or SIGABRT while free memory operation. There are multiple repeated core in the customer environment during memory allocation/free operations. This issue will be triggered only when the size of the cookie in the http request is more than 4095. So if the cookie is more than 4095 in length the trailing '\0' corrupts the heap memory. If '\0' overwrites a memory chunk that is already in use, then it might cause an intermittent error like this.
EAM process cored and restarted.
In EAM plugin, when the size of the cookie in OAM http request is more than 4095.
This issue has no workaround at this time.
The EAM module now continues to function correctly when the size of a cookie in the HTTP request is greater than 4095.
