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 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.
With Regards
Venkat
