Description:
Symptoms ... TMM cores due to Out of Memory (OOM), and xdata is the majority of the memory consumption. ... Impact ... (Massive xfrag usage, degraded performance, eventual TMM OOM.) ... Conditions ... The SSL enters a failure mode where it appears to transmit alert messages repeatedly until TMM is OOM, which causes the transmissions to stop due to lack of memory. ... TMM then cores due to lack of memory. ... Workaround ... Fix Information ... Clear codec alert after propagation so SSL filter no longer reports alerts indefinitely. ... Behavior Change
