The vCMP worker-lite system is unable to reattach to the host after errors or timeouts occur between the vCMP guest and host.


SSL and compression traffic does not pass through an affected vCMP guest.


This issue affects worker-lite based systems running vCMP guests at 11.4.1 HF6 or 11.5.1 HF6 with any version of BIG-IP running in the hypervisor. Affected systems are PB200, B2100, B2150, and B4300 Viprion blades.


To resume SSL and compression traffic processing, the guest tmm process must be restarted, either by issuing 'bigstart restart tmm' within the vCMP guest, or by taking the guest to a provisioned state then back to deployed from the hypervisor.

Fix Information

An issue has been corrected that might have prevented a vCMP guest from processing SSL and compression traffic.
