Hi All , After I load xeno_psos.ko by "/sbin/insmod xeno_psos.ko", and run my test program, whic create a queue by "q_vcreate", but not delete it in the test program. After I finish running my test program. Then I unload the xeno_psos and then reload it again, it will crash as follow: /sbin/rmmod xeno_psos Xenomai: stopping pSOS+ services.

Thanks. Best regards, Wenyi Gao
