Re: [Pharo-users] RFB on 2.0 + linux - semaphore primitive failed
OK. I think I am having the same issue here. I am using Pharo2.0 Latest update: #20619, and a Mac VM of Mar 13 2013. I have a SmalltalkHub image running with RFB. If I save the image with the RFBServer running, my image freezes. If the server is stopped while saving, there is no problem. The hung seems to be AFTER the image save itself, because if I kill the process and start again, the image was saved. Does somebody remember if this was solve or not? if not, I will try to debug a bit.

Kind regards, Paul I ended up reverting back to Pharo 1.4 and don't have plans to use Pharo 2 in production. If you do not give us more information we will never be able to fix it. And may be 3.0 will still have the problem and you will start using system that is 3 year old. I can understand that you get in a situation where you cannot do otherwise but do not expect us to fix magically things.

[Pharo-users] RFB on 2.0 + linux - semaphore primitive failed
Hi - In Pharo2 do I need to stop and start the RFB server? I 've been getting a primitive #signal in Semaphore failed error after the image starts. I'm using this version of RFB RFB-MarianoMartinezPeck.41 Thanks Paul
Re: [Pharo-users] RFB on 2.0 + linux - semaphore primitive failed
Maybe this is related to #maxExternalSemaphores: ? Did you try sending a large number? For my seaside images where I have RFB I do: Smalltalk vm maxExternalSemaphoresSilently: 65535.

Re: [Pharo-users] RFB on 2.0 + linux - semaphore primitive failed
I don't know. I don't get the errors that used to occur with the max semaphores being exceeded. I thought Igor Stasenko fixed that issue in the VM so the array that holds the semaphores grows without blocking. Or something. What I do know is that if I 'abandon' that warning and save quit and then reopen the image then the UI is locked and I have to use Seaside's WAScreenshot tool to suspend and resume the UI to unfreeze it.

There is no limits and maxExternalSemaphoresSilently is just does nothing and ignored. What I do know is that if I 'abandon' that warning and save quit and then reopen the image then the UI is locked and I have to use Seaside's WAScreenshot tool to suspend and resume the UI to unfreeze it. weird. i would start from figuring out, why primitive failed..and for which semaphore. -- Best regards, Igor Stasenko.
