RE: [Devmon] Inappropriate ioctl for device

Made a little progress on this, last night. I was able to reproduce this problem on our RHEL2 box last night. Apparently it is caused by opening a file before your fork (even if you close it prior to forking, you still get the=20 error). I don't have a fix for this yet (I cant avoid opening a=20 file before I fork in Devmon); I'll keep investigating. -Eric Schwimmer Network Engineer UVA HSCS Network Engineering =20 > -----Original Message----- > From: dev...@li...=20 > [mailto:dev...@li...] On Behalf=20 > Of Schwimmer, Eric E *HS > Sent: Monday, February 27, 2006 10:09 PM > To: dev...@li... > Subject: RE: [Devmon] Inappropriate ioctl for device >=20 >=20 > Hrm.
