OpenMax() returns 1073741816 when called via javascript exec() in obsidian plugin

[hakonhagland]

I wrote an obsidian plugin that uses exec() to run a perl script that uses Proc::Daemon to start program. However, the program took forever to start (more than 5 minutes), it turned out that the reason was that the OpenMax() returned 1073741816 in the closing filehandle loop:

Proc-Daemon/lib/Proc/Daemon.pm

Line 225 in 5e53ec4

foreach ( 0 .. OpenMax() ) {

whereas it returns 1024 if I run the script from the terminal (not via obsidians exec()). Any idea why this happens and how to solve it?
