I use Net_Gearman from PECL, Gearmand 1.1.11 and Gearman Manager. Every time I add background job, I can see new worker listed with no Function, nor Id in Ggearman-Monitor:

enter image description here

If I add many messages in the bash loop, after some time it becomes very slow.

for i in $(seq 0 9999); do php Client.php && echo $i; done

Yesterday, the situation was even worse - I had many error messages in Gearmand log regarding Too many open files and once I added --file-descriptors=49152 as an option and swithched to 1.1.11 from 1.0.6, these errors gone.

Here is lsof -p $(cat /var/run/gearman/gearmand.pid) output:

Net_Gearman is the pear package not pecl. I have had this similar issue with Net_Gearman pear package and because of that I am planning to try pecl "gearman" extension. So can you just confirm the issue is with pecl extension "gearman" or pear library "Net_Gearman"? –  Makailol Aug 6 at 3:59
    
I can confirm I'm not going to use it anymore. –  Roman Newaza Aug 7 at 1:37
