We are seeing the above error quite frequently during uploads

following guidance from the interwebs i set:

startup --host_jvm_args=-XX:MaxDirectMemorySize=512m

altho that doesnt seep to have helped (fwiw i noticed an errant " so will remove and see if that does help after all)

phlax commented

seems like this may be more of a bazel issue - i switched to using google RBE and got a similar result

I think you're right- this is happening on the client/bazel side.

thanks - i raised it upstream so will close here
