bitcoind json rpc getting stuck sometimes

[btc_enigma]

Hi,

Sometimes bitcoind json rpc just gets stuck and don't respond to bitcoind getinfo calls.
When I see .bitcoin/debug I can see that bitcoind is still running and processing blocks correctly

I am using bitcoind 90100. What is the best way to fix this, instead to kill and restarting bitcoind ? I am facing this every few days

are you running the daemon on a vps?

I have similar issues and I suspect its because I run it on a VPS.

yes correctly, thats why i was asking him.

@shorena: can you post something about the config you were using @VPS (OS, RAM, CPU, HDD).
just out of curiosity: did you have this issue on ubuntu?

Yes its Ubuntu 14.04.1 LTS, with 2GB Ram, single core CPU and 50 GiB SSD. I have no idea which SSD/CPU they use and the ISP changed the offer by now. Its a deal I only got because I study IT/SC at my university. We theyd charge me the regular amount Id be well known to their support by now.

The picture below shows nicely how sometimes the shellscript gethering data from bitcoin core does not finish within 30 seconds. The white spots are unknown values / no data which occure when the script can not finish to feed the database. I thought about giving it more time as it runs every minute, but I dont think it should run that long. I never had this issue on any other machine, but every other machine is also a bare metal one and is not running 24/7 (yet), thus I suspect its because I have a cheap VPS any my priority on the machine is very low.

Yes, I am running on VPS
Ubuntu 13.10, 2G RAM

Update, now I have upgraded to bitcond 90300 , this seems to have fixed the issue. Didn't see any hangs for last three days. CPU usage also low
