dotnet-dump fails with "Writing dump failed (HRESULT: 0x80004005)" in Ubuntu

2

Despite I run dotnet-dump under root, and process is run under root (see service description below), it seems I lack some permissions. I tried also other directories in home, in var and in tmp: all the same message.

root@DSK06511:/home/monouser# dotnet-dump collect -p 10131 --diag -o /var/tmp/MyNodeDump/
Writing full to /var/tmp/MyNodeDump/
Writing dump failed (HRESULT: 0x80004005)

root@DSK06511:/tmp# dotnet-dump collect -p 10131 --diag -o /home/monorepo/tmp/
Writing full to /home/monouser/tmp/
Writing dump failed (HRESULT: 0x80004005)

They had similar issue here but they solved it with --output to the directory in /tmp, which didn't help

Please check in the directory of your service, the permissions of createdump, it requires execution rights to work, if it looks like this:

ls -l | grep 'lib\|create'
-rw-rw-rw- 1 root root  109656 May 20 00:40 createdump

You have to grant the execution rights:

sudo chmod u+x createdump
