Once more than 1 worker core is added in startup conf, crash is not observed
during init phase. But when I set the async mode on, it crashes in same place.
Do I need to set async mode on to use QAT ? Do I need to enable any specific
plugin ?
cpu
{
corelist-workers 9-12
main-core 13
}
DBGvpp# set ipsec async mode on
