Hi! I am continuing my search of why does my remote headless image run out of semaphores eventually. I have found the culprit this time. It is most definitively related to RFBServer. I am using version 38 from http://source.lukas-renggli.ch/unsorted. Every time I disconnect from the image with my VNC client (I click the disconnect icon) the count of leaked semaphores increases by 3. Since there is 3 semaphores per socket, I guess this is related to sockets. Now what do I do? What do I check? I am running the a Pharo image and Cog I got from CI server yesterday. This is the script I use to count leaked semaphores: | semaphores arr res | arr := ExternalSemaphoreTable unprotectedExternalObjects. semaphores := arr reject: #isNil. res := semaphores collect: [:sema | sema pointersTo reject: [:ptr | ptr == arr or: [ptr == semaphores ] ] ]. res := res select: [ :each | each isEmpty ]. res size. -- Milan Mimica http://sparklet.sf.net
