Apache httpd 2.4.34 couldn't receive signal SIGTERM on SuSE 15
I have install apache httpd 2.4.34
on SLES 15
, and there are six httpd
processes running.
When I send signal SIGTERM
to httpd
process, all the six httpd
process couldn't receive signal SIGTERM
(I had gdb
attched httpd
process to catch signal SIGTERM
),
but I find kill 15 11143
return 0 via command strace. But httpd could reiveive signal SIGKILL
, it's very strange.
And apache httpd 2.4.34
running on other platform(SLES12, SLES11, RHEL7
) could reiveive and handle signal SIGTERM
normally.
Does anyone encounter this phenomenon?
