The output is random bytes in hex.
It looks good.
Sometimes this fails if openssl is unable to write to a temp file

Thanks John for quick response.
But can you let me know, what should be o/p of this command?
I tried on 2 systems and see below output.
/home/root# openssl rand -hex 8
d2749a6620672899
/home/root#
/home/root# openssl rand -hex 8
d74e404a57e57ae9
/home/root#
Right now, I dont have failed system in handy and so dont know, what should be the output of above command?
Hi
This may be related to an openssl problem
try
openssl rand -hex 8

Hi All,
We are using httpd version 2.4.46 and its working fine for a long time. But recently, we started seeing an issue where apache hangs indefinitely even when the system is in idle
state.
And when apache hangs, I see below entries in error_log:
[Tue Sep 21 22:05:53.243013 2021] [ssl:warn] [pid 5769:tid 2644435888] AH01990: Server: PRNG still contains insufficient entropy!
[Tue Sep 21 22:05:54.501476 2021] [ssl:warn] [pid 5769:tid 2787111856] AH01990: Server: PRNG still contains insufficient entropy!
[Tue Sep 21 22:05:54.502449 2021] [ssl:warn] [pid 5769:tid 2787111856] AH01990: Server: PRNG still contains insufficient entropy!
I am pretty sure, we not changed anything related to httpd config for quite a time time and have no idea, why this issue started getting manifested now.
Please help me how to RC this and what logs can be looked to debug further?
PS: Occurence of issue is more in systems where FIPS is enabled. In FIPS disabled systems, occurrence is less.
