TMM could crash when sending CSS files through a virtual with LTM URI Translation profile. This happens if CSS parser does not have enough input data to finish processing of current chunk and remains in a certain unfinished state. CSS will try to parse remaining data again starting from that incorrect state and will crash after that.
Traffic disrupted while tmm restarts.
Specific data at the end of current chunk of backend response.
This issue has no workaround at this time.
Resolved issue where rewrite CSS filter/parser may use stale iovs in declaration_state resulting in SIGSEGV.
