ERROR DESCRIPTION:
The MPROUTE server intermittently terminates with messages:
PSA: Unable to create the timer thread to process user
exit...!.
PSA: errno (132) errno2(0).
DTCMPR7807I Abnormal termination - out of storage
DTCMPR7839I OSPF receive thread terminates
DTCMPR7839I Informational receive thread terminates
Increasing the storage size of the server virtual machine does
not alleviate the problem, but only prolongs termination of
the server. From these symptoms, it appears that some
storage is not being freed after use.
LOCAL FIX:
PROBLEM SUMMARY:
****************************************************************
* USERS AFFECTED: All users of MPROUTE *
****************************************************************
* PROBLEM DESCRIPTION: When a multipath route is found but *
* not used, storage for the structure is *
* not released. *
****************************************************************
* RECOMMENDATION: APPLY PTF *
****************************************************************
When MPROUTE receives information about a route that already
exists in its tables, it creates an MPATH structure to store
the new route while deciding while deciding whether or not
to use it. In the case where MPROUTE does not use the route
(either because the level of MPROUTE running does not
support equal cost multipath (pre-430) or the limit of
multipath routes has been reached) the storage for the MPATH
structure was not being released and would eventually cause
MPROUTE to run out of storage.
PROBLEM CONCLUSION:
Now, in the case where an allocated MPATH structure is not used,
the storage is released before MPROUTE processing continues.
