For GC logs I think I can just change the ignite.sh script in /usr/share/apache-ignite/bin ??? Like right now I have a "heavy" load running and everything seems to be fine... Ok I'll check if it happens again On Wed, 28 Aug 2019 at 11:21, Ilya Kasnacheev wrote: > Hello! > > Well, my

Hello! Well, my recommendation is to find a way to enable GC logs and collect regular logs as well, from all nodes. Regards, -- Ilya Kasnacheev ср, 28 авг. 2019 г. в 18:18, John Smith : > The drop box link here: > https://www.dropbox.com/s/etm61xeb9mghs9m/ignite-details.log?dl=0 > > Didn't

The drop box link here: https://www.dropbox.com/s/etm61xeb9mghs9m/ignite-details.log?dl=0 Didn't take any logs just some visor printout and some Linux command printouts and cat some info/stats from the logs just to be sure I wasn't reading the wrong values. Everything else as far as am aware is

Hello! Don't see any logs here. This setting may be problematic because you consume 14 out of 16GB by a single Ignite process so system may decide to swap something out. I recommend decreasing heap to 2G if possible. Should also make GC faster. I'm not sure how to enable GC logs when running a

Hi, Now I have set the failure detection timeout to 12 mills and I am still getting this error message intermittently on Ignite 2.6 version. It could be the network issue but I am not able to confirm that this is happening because of network issue. 1) What are all possible reasons for

Hello! It's hard to say what happens here. Do you have GC log? Please make sure to collect it. Is there anything running in the same JVM with Ignite? Regards, -- Ilya Kasnacheev ср, 28 авг. 2019 г. в 15:13, John Smith : > I'm not doing anything fancy with the cache I have 3 million records

I'm not doing anything fancy with the cache I have 3 million records partitioned cache over 3 servers. And all I do is some put and gets. Unless I have a bad config? On Wed., Aug. 28, 2019, 6:32 a.m. Ilya Kasnacheev, < ilya.kasnach...@gmail.com> wrote: > Hello! > > Well, it's pretty descriptive.
