The customer's network recently experienced an outage, and found all the session end reason was resources-unavailable ;
I exec the comand " debug dataplane pool statistics" and found there is a parameter in the software pool called Regex Results that has been exhausted. Compared with normal firewalls, this value should not be reduced. I also tried to execute “set deviceconfig setting session resource-limit-behavior bypass” , but this solution is not acceptable to customers.
At present, the customer's system version is 9.1.13 of the PA3000 series, which has been rolled back to 9.1.12, and the parameters are normal
Does anyone know if this is a bug?
Customer needs an official explanation，thanks in advance！
Thank you for the post @miaocongcong
I experienced exactly the same issue in mid of February after I upgraded PA-3220 to 9.1.13. The command you executed: "debug dataplane pool statistics" is the right way to drill down the issue. As an immediate measure we failed over the Firewall and rebooted the one that was having an issue and opened a TAC case. After spending some time on the call, TAC advised to downgrade the Firewall that solved the issue, however we could not get anything official regarding bug. Based on the input from TAC, in version 9.1.13 there were some issues that engineering team is looking into, but there is no official bug id for this.
