A log message in /var/log/tmm similar to the following: Assertion 'Hash type successfully set' failed.
Tmm may initially fail to start, log an SIGFPE, and then might or might not start normally afterwards. Traffic disrupted while tmm restarts.
A vCMP guest running either: - v13.x release of 13.1.3.6 or later - v12.x release of 12.1.5.3 or later A vCMP hypervisor that is running: - v13.x release of 13.1.3.4 or lower - v12.x release or 12.1.5.2 or lower - v11.x release Any vCMP guests running v14.x or later are not affected.
Either: -- Upgrade the vCMP Hypervisor to the latest release. -- Upgrade the guest to v14.1.0 or later. It may also help to remove the cached libdag on the guest, and restart tmm by running the following commands on the guest: rm -f /var/run/libdag.so_* && bigstart restart tmm
TMM no longer crashes during startup with SIGFPE
