Re: [Pharo-users] Voluntarily cancelling requests ("applying an expiration date")

Hi Holger, That is a complicated story ;-) But, you running out of external semaphores means that you are using too many sockets, are not closing/releasing them (in time) and/or your GC does not run enough to keep up (it is easy to deplete the external semaphore table without the GC kicking in

Re: [Pharo-users] P3 and concurrenty

Yes, I see - that sounds sensible. Could it be an idea to subclass the pool-class and to prepare statements in this method, if there is a kind of init-method in the class? What do you think? Petter On Mon, Feb 10, 2020 at 4:36 PM Sven Van Caekenberghe wrote: > > > > On 10 Feb 2020, at 16:30, P

You are welcome. This is really one of the few resources on the topic and at this level in the ecosystem. In the future I plan to learn and explain monitors because they are better than semaphores or mutexes but I have the learn about them before :). > On 10 Feb 2020, at 20:46, Todd Blanchard
