#22959: Too many open files error while doing a mass forced upgrade -----------------------------------------+---------------------------------- Reporter: dave.evans55@… | Owner: macports-tickets@… Type: defect | Status: new Priority: Normal | Milestone: Component: base | Version: 1.8.1 Keywords: force upgrade | Port: -----------------------------------------+---------------------------------- I have 641 ports installed. I deleted all the inactive ports. I then ran a command to force upgrade them all with the +universal variant: script bigbuild.log sudo port -pdk upgrade --force installed +universal After a few hours of compilation an error occurred: ./libtool: cannot make pipe for command substitution: Too many open files I increased the ulimit(1) open files limit for the process from 256 to 10000 and ran the upgrade command again. While it was running I monitored the open files for the tclsh process using lsof: I noticed that there were a lot of instances of /opt/local/var/macports/receipts/file_map.db open. I counted them with: sudo lsof | grep -i tcl | grep receipts | wc -l and there were 272 instances of this file open. I think there is an open file leak in port. -- Ticket URL: <http://trac.macports.org/ticket/22959> MacPorts <http://www.macports.org/> Ports system for Mac OS
