Bug #80050 [NEW]: msg_receive is awakened by error code 43

From: milan dot matejcek at gmail dot com Operating system: raspbian / ubuntu PHP version: Irrelevant Package: Semaphore related Bug Type: Bug Bug description:msg_receive is awakened by error code 43 Description: ------------ sysvmsg extension I tested on arm raspbian buster 10, 32 bit (php 7.3.19) and ubuntu 20.04, 64 bit (php 7.4.9), both are same. I have long running process, which is executed by supervisor, where is passive waiting for message from queue, but this waiting is sometimes awakened by error code 43. I checked that the supervisor runs only one php process and the PID is still the same. Is there anything what clean resources or queues? If i have two processes and different queue key, than both return error 43 in same time. Test script: --------------- I create repository on Github: https://github.com/h4kuna/msg Expected result: ---------------- Passive waiting without awakened -- Edit bug report at https://bugs.php.net/bug.php?id=80050&edit=1 -- Fix committed: https://bugs.php.net/fix.php?id=80050&r=fixed Fixed in release: https://bugs.php.net/fix.php?id=80050&r=alreadyfixed Need backtrace: https://bugs.php.net/fix.php?id=80050&r=needtrace Need Reproduce Script: https://bugs.php.net/fix.php?id=80050&r=needscript Try newer version: https://bugs.php.net/fix.php?id=80050&r=oldversion Not developer issue: https://bugs.php.net/fix.php?id=80050&r=support Expected behavior: https://bugs.php.net/fix.php?id=80050&r=notwrong Not enough info: https://bugs.php.net/fix.php?id=80050&r=notenoughinfo Submitted twice: https://bugs.php.net/fix.php?id=80050&r=submittedtwice register_globals: https://bugs.php.net/fix.php?id=80050&r=globals PHP version support discontinued: https://bugs.php.net/fix.php?id=80050&r=phptooold Daylight Savings: https://bugs.php.net/fix.php?id=80050&r=dst IIS Stability: https://bugs.php.net/fix.php?id=80050&r=isapi Install GNU Sed: https://bugs.php.net/fix.php?id=80050&r=gnused Floating point limitations: https://bugs.php.net/fix.php?id=80050&r=float No Zend Extensions: https://bugs.php.net/fix.php?id=80050&r=nozend MySQL Configuration Error: https://bugs.php.net/fix.php?id=80050&r=mysqlcfg
