[otrs] Got "out of memory" error trying to open "package management"

Got this error when tried to open package management link in admin mode. httpd-error.log: [Tue Feb 15 18:07:35 2011] [error] [Tue Feb 15 18:07:35 2011] -e: Out of memory during "large" request for 8392704 bytes, total sbrk() is 102219776 bytes at /usr/local/otrs//Kernel/System/XML.pm line 711.\n Page output (apache's) Out of memory during "large" request for 8392704 bytes, total sbrk() is 105971712 bytes at /usr/local/otrs//Kernel/System/XML.pm line 711. BTW, I installed additional OTRS modules like ITSM, FAQ, CMDB previously. May be there's some way to clean my DB from them? -- WBR, A.Rymkus
