During start-up, tmm may go into a restart loop and never come up fully.
Traffic disrupted while tmm restarts. tmm on the host goes into a restart loop due to lack of memory. Signature in the log files is similar to "notice Too small memsize (90) -- need at least 136 MB" tmm on the guests core with tmm log entries: notice panic: vdag failed to attach notice ** SIGFPE **
This can occur on both the vCMP host and guest, usually during the first or second boot of the upgraded software. The existence of /mprov_firstboot and a provision.tmmcountactual set to an incorrect value is an indication that this is occurring.
