Hi guys I have nonstartable Pharo 1.3 image, is there any way to get it started? This image was running all the time, being on the net directly (Aida based web development image) and snapshoting every hour. The problem happens at such snapshot, raising Not enough space for external objects/too many semaphores error and block. After I killed it, snapshoted image is not startable anymore, more exactly: it starts in blank window and stays unresponsive. Is this too many semaphores error related to too many open sockets problem we discussed not to long ago? Any help greatly appreciated. Not to mention finding a bug and removing it forever, because Pharo should become stable as a rock, as VW for instance is :) Best regards Janko PharoDebug.log: THERE_BE_DRAGONS_HERE Error: Not enough space for external objects, set a larger size at startup! 4 October 2011 4:00:01 am VM: unix - i686 - linux-gnu - Croquet Closure Cog VM [CoInterpreter VMMaker-oscog.35] Image: Pharo1.3 [Latest update: #13299] SmalltalkImage(Object)>>error: Receiver: Smalltalk Arguments and temporary variables: aString: 'Not enough space for external objects, set a larger size at startup!'...etc...
