I have tried increasing my paging memory to min 5GB max 10GB and it still doesn't work (computer has about 3GB of regular memory available).

Strange... sbt has been one thing that has been rock solid for me over the last several builds. What version of sbt are you using? Do you have a custom launch script? What happens if you do sbt -mem 2048?

[pradyuman]

I'm using sbt 13.13 with no launch script. I'll try with sbt -mem 2048 and get back to you.

Having the same issue... sbt -mem 2048 doesn't help. Btw, despite exceptions, sbt (and console) actually starts and basic commands work. But anyway that's not normal

[pradyuman]

Yeah sbt -mem 2048 didn't fix anything for me either.

[vladbat00]

Update. Sorry, my issue is a little bit different. I have the same exception messages, but I receive them on sbt start, but not after some time..

I'm trying to run the sbt console, and after some time, the sbt console stops working with a "Cannot allocate memory" error.

[pradyuman]

Ah ok. sbt will start for me as well (with the memory exceptions) but it's very inconsistent with when commands will actually run in the console and when everything just fails.

Make sure you have enough memory for SBT as well:

export JAVA_OPTS="-Xmx2G -Xss2M -XX:MaxMetaspaceSize=512M -XX:ReservedCodeCacheSize=192M -Dfile.encoding=UTF-8"
