Symptoms

By default, the 'rewrite' profile is in APM portal mode. When enabling a 'rewrite' profile on a vCMP guest with ten cores allocated all layer 3 connectivity to the virtual IP will begin to fail. Errors similar to the following are seen in the TMM log (/var/log/tmm): notice share_mem: shmget(0x1304d8, 657664, 0x3b6): Invalid argument The system posts errors similar to the following in Local Traffic logs (/var/log/ltm): crit tmm1[17820]: 01000025:2: Device error: mpi failed to allocate shared memory err tmm1[17820]: 01480043:3: Failed to build plugin profile for /Common/rewriteplugin err tmm1[17820]: 01480002:3: Can't initialize plugin configuration crit tmm1[17820]: 01000203:2: Proxy failed to attach plugin rule err tmm1[17820]: 01000008:3: Proxy initialization failed for /Common/my_virtual

Impact

When a 'rewrite' profile using the default settings is attached to a virtual server all layer 3 connectivity to the virtual IP will fail.

Conditions

A 'rewrite' profile in portal mode (the default) on a vCMP guest with ten cores allocated. A 'rewrite' profile is required for rewriting content; this is required for APM Portal deployments and VDI deployments.

Workaround

Use another core allocation configuration for the guest (such as two, four or eight). If the APM (portal) function is not required, create a custom 'rewrite' profile with the 'rewrite-mode' option of 'uri-translation'.

Fix Information
