maven - Jenkins FATAL ERROR Timeout: killed the sub-process -

i running jenkins job creates findbugs report. seems findbugs memory , time hungry facing outofmemory error issue , increased memory setting maven_opts variable i.e.

maven_opts=-xms512m -xmx1024m -xx:maxpermsize=512m. 

now facing timeout: sub-process interrupted exception. suggestion how rid of this?

note: using "mvn clean compile findbugs:findbugs" command , if run manually working(without timeout exception).

findbugs version: 2.5.3 jenkins version: 1.545

here error log:
