[stunnel-users] CPU 100%

[Vincent Deschenes]

Just a silly idea, but is it possible you have a re-entrant configuration for one service, one that connect back to itself creating a loop?

Subject: [stunnel-users] CPU 100%

We are running stunnel 5.49 on FreeBSD 11.2 and we're running into a problem once in a while.

CPU pegs at 100% when we get an stunnel connection from one of our external devices.
This affects 100% of all cores and we can't even log in to console.

To mitigate this temporarily, we have a script running in the background to watch when stunnel begins to spike and restarts the daemon.

It doesn't happen 100% of the time, and so far I have been unable to distinguish what makes the connection do this to the CPU.

Have any of you run in to this issue?


Sincerely,


Brian Murrey
System Engineer II, IT Infrastructure
