@bluezod Is it possible for you to open these core dumps with gdb and give us a backtrace? Like |

Thanks for the response @bwoebi Here is the output I got following your debug instructions: |
|
I am using Kubernetes, and when deploying the latest version, memory fills up in several pods sequentially within 10 minutes, causing OOM errors. The cause is unknown, but it does not occur in version 1.3.1 for now. |

@neoty We have observed (via our telemetry) that for some users the dd-ipc-helper process is using too much memory (but we do not know why yet). We do kill the process, once it reaches 1 GB of RSS memory used as a stop-gap measure, but maybe that's too much for you? |

@bluezod Looks like it's related to an dd-trace-php/appsec/src/helper/runner.cpp Line 148 in 3f3547d |

Currently, due to stable operations and policies in place, additional testing is challenging (apologies for not being able to assist further). However, we do have the following information: |

They're shared across all inheritors on PHP 8.1+ and thus only need to be incremented on the specific ce. This issue arises when a property from an inherited internal class extending Exception is itself inherited by another class. Also fix an accidentally discovered use-after-free with peer.service. Fixes #2898. Signed-off-by: Bob Weinand <[email protected]>
|
@bluezod @mirkojoshua We've released 1.4.2 which will fixes both things. @neoty I suppose what you observe matches #2902. I'll track that there. |

@bwoebi (my prev tag was wrong :p) thank you! |
