when I run the TOP command in terminal - I can see two of the vhosts using most cpu% like this PID USER PR NI VIRT RES SHR S %CPU %MEM TIME+ COMMAND 9176 web132 20 0 1063688 42228 4420 S 1198 0.3 18646:58 phpUMI6bM_w7usn so against percentage cpu it is 1198 and against command it is phpUMI6bM_w7usn so can a single process use so much of cpu. when I tried find the path of the process. I traced it down to vhost/tmp folder. there were so many temp files were there like Code: ca_dompdf_img_A8qF2q ca_dompdf_img_f9OQPx ca_dompdf_img_kjjs9o ca_dompdf_img_pS6ydz ca_dompdf_img_UyISzh gifdompdf_img_VEaW3M.png ca_dompdf_img_a92e9c ca_dompdf_img_F9YD2G ca_dompdf_img_KJnmUe ca_dompdf_img_psEeBe ca_dompdf_img_Uykzps gifdompdf_img_vrCWGz.png How can I resolve this issue? Update: I have completely disabled the client and web in ISPCONFIG, but I can still see the same process running under the same vhost. Also tried kill 9176 - but the process still running.
