I think they tried improving the streaming support and jammed everything into memory and causes overflow - i downgraded to 1.0.9 and disabled auto update using the env variable. I think it's working? Although, it's painfully slow today for some reason (Opus model). 1.0.10 is def broken i think.

Also Claude trying to run bash commands on its own is extremely slow for some reason, and sometimes it doesn't know that command completed, resulting in 2m timeout although it was completed, so annoying. I'm on the 20X max plan

sry mate, but how did you downgrade? im trying to do the same, but no luck so far

dayowe · 1 year ago

@juggerke npm install -g --force --prefer-online @anthropic-ai/claude-code@1.0.9

I see this also frequently in 1.0.10 .. especially when writing new files

juggerke · 1 year ago

@dayowe thank you mate.
yeah, it also happens for me. its very interesting, that sometimes its crahes, i do claude --resume, then ask for the same prompt on the same file, and nails it perfectly.

We believe this should be mitigated in the latest release, v1.0.15. Please update and give it a try.

Can anyone confirm if this works? Today I moved to @anthropic-ai/claude-code@1.0.9 and it worked.

patrickrho · 1 year ago

works for me, the ctx per read i think has been reduced to 25000 but works better

dayowe · 1 year ago

@rboyce-ant seems resolved! Thanks for fixing this

lehoanganh298 · 1 year ago

@rboyce-ant I have v1.0.17 have this error (occur consistently with the same prompt). I downgrade to v1.0.15 and it worked (not have the OOM crash error anymore. although it still attempt many times to read the whole large dataset files and have error Error: Cannot create a string longer than 0x1fffffe8 characters even when I tell it to not read large files in the prompt).

So apparently the later versions don't have the fixes included in v1.0.15

I also experience the same error in v1.0.22. It doesn't fail like this with older versions

Same issue on 1.0.22:

Interestingly, downgrading to 1.0.9 and then back to the latest seems to have fixed the issue for me (at least for now!)
