Ubuntu 14.04, HHVM 3.10.1
df -h I can see the following:
Filesystem Size Used Avail Use% Mounted on udev 7.9G 8.0K 7.9G 1% /dev tmpfs 1.6G 1.6G 8.0K 100% /run /dev/xvda1 9.8G 2.1G 7.2G 23% / none 4.0K 0 4.0K 0% /sys/fs/cgroup none 5.0M 0 5.0M 0% /run/lock none 7.9G 0 7.9G 0% /run/shm none 100M 0 100M 0% /run/user
What's taking up the full space in tmpfs is actually the file
/run/hhvm/hhvm.hhbc which is 1.6 GB currently. Is this healthy? It does not look like it is.
I have found the following, related to the full tmpfs: https://github.com/hhvm/packaging/issues/132
"On my Ubuntu (14.04) /var/run is a tmpfs mount that's only 400MB in size. The hhvm.hhbc file grew to a little over 350MB on one system. I think it may make more sense to default to putting this file under /var/cache/hhvm instead."
My central path is just as explained, defined to /var/run/hhvm/hhvm.hhbc - but i do not have a /var/cache/ in my filesystem, so i wonder if i really should change the central path to /var/cache/hhvm instead? Also, wouldn't this be bad / not be temporary since tmpfs is mounted to only /run?
I am debugging since my HHVM is crashing periodically, which requires that i run a reboot of hhvm service/remove the hhvm.hhbc before everything works again.
