Hi! In a 2.4.1 XE/XEM installation with contents recently migrated from a XE 1.3.8295 I'm seeing this: top - 12:15:06 up 16 days, 8:38, 3 users, load average: 1.36, 1.39, 1.32 Tasks: 1062 total, 1 running, 1061 sleeping, 0 stopped, 0 zombie Cpu(s): 7.8%us, 0.2%sy, 0.0%ni, 92.0%id, 0.0%wa, 0.0%hi, 0.0%si, 0.0%st Mem: 6216784k total, 5992440k used, 224344k free, 95312k buffers Swap: 2104472k total, 152k used, 2104320k free, 3222044k cached PID USER PR NI VIRT RES SHR S %CPU %MEM TIME+ COMMAND 17689 root 22 0 668m 550m 2852 S 100 9.1 216:28.00 java Java goes back to "normal" if I shut down the Tomcat instance on which XWiki is running. Catalina.out is plenty of errors and warnings and I really don't know which of them, if any, could be responsible of this situation. Lucene is not working neither. I'm linking a catalina.out file truncated by yesterday at 22:19 after a Tomcat shutdown. Please, could you help me to work out this errors and warnings? http://ftp.ebiotic.net/fromPeat/catalina.out.201010211227.txt Thanks for your help! Ricardo -- Ricardo Rodríguez CTO eBioTIC.
