#15 Regular crashes on Fedora 19

[romu70]

I run PhpVirtualBox 4.3 (so with VB 4.3) on a Fedora 19 computer, and I'm facing regular crashes of PhpVirtualBox, which appears several times per day.

When a crash occurs, the popup error message is:
"An error occurred communicating with your vboxwebsrv. No more requests will be sent by phpVirtualBox until the error is corrected and this page is refreshed. The details of this connection error should be displayed in a subsequent dialog box."

After clicking on "OK", there is another error popup:
"Error logging in to vboxwebsrv."

Here there is a "details" button which gives the here attached stack trace.

Any help will be appreciated, thanks.

Additionnal information: to remove this error (until the next time it'll appear), I log in the computer, restart the vboxweb service, and then, refresh the page.

Hi. Exact same behaviour on CentOS 6.5 (2.6.32-431.3.1.el6.x86_64).

/usr/lib/virtualbox/vboxwebsrv is VirtualBox file, but not phpvirtualbox.
Ask on VirtualBox's bug tracker.

What VVD said. This is a VirtualBox issue.
