Hello,
I have a problem on a managed server on OVH.

Have any idea?
Thanks, Michele

Hey there! You can ignore the "entropy is low" warning as that seems to be unique to Solr in modern times:
Do you see any additional information around the time this happened inside the cPanel log (/usr/local/cpanel/logs/error_log) that could indicate why it failed?

I'm encountering a similar issue with a managed server on OVH. I've observed similar log entries regarding Solr for cPanel Dovecot, particularly the warning about low available entropy. It seems like this warning might be related to potential issues with features like UUIDField, SSL, or other functionalities that rely on proper RNG operation.
One potential way to check for the available entropy is by using the command 'cat /proc/sys/kernel/random/entropy_avail', as suggested in the log entry. However, I'm still investigating potential solutions to address this issue effectively.
Interestingly, this low entropy issue reminds me of troubleshooting randomness-related problems in creative software environments—like when exporting high-resolution videos with CapCut Video Editor on certain Linux setups, where entropy-related delays can impact processing performance. I’ve seen similar discussions over at capprocutapk.com, where users explore tweaks and modded versions to enhance performance. Though the context is different, both scenarios underline how critical system entropy can be for smooth operation.
Have you made any progress in resolving this problem on your end? I'm eager to hear any insights or solutions you might have come across. Let's collaborate to find a resolution to this perplexing issue.

Hi Joe,
thanks for your help, for now any progress.
The value of entropy_avail is 256

Are you familiar with the warning messages regarding low entropy levels on your managed server through OVH? Despite the Solr for cPanel Dovecot service starting successfully, these warnings suggest potential issues with features like UUIDField or SSL that rely on proper RNG operation. Have you explored methods to increase available entropy, and if so, what steps have you taken to address this concern? Let's collaborate to troubleshoot and resolve this issue effectively.
