API Umbrella postrotate command fails on nginx access.log

[mnguyen9]

API Umbrella Version: 0.14.2 The postrotate command api-umbrella reopen-logs is failing to reopen Nginx access.log. After logs are rotated, the rotated file is created and access.log is empty. However, the service does not write to access.log anymore. If I run the command, it hangs and cancelling it gives the following error: Executing command failed: perpctl -b /opt/api-umbrella/etc/perp 1 nginx.

That command along with perpctl -b /opt/api-umbrella/etc/perp hup nginx hangs when ran on their own.

Logrotate config:

# Rotate all the perp stdout/stderr logs, as well as any logs that can be
# reopend via the "api-umbrella reopen-logs" command.
