Reboot durch Push-Service in der Nacht

[matze1985]

Hey Leute,

seit dem ich vor ein paar Tagen das Update auf 54.04.80freetz-devel-4252M gemacht habe, habe ich leider tägliche Reboot um kurz nach 0 beobachten müssten.
Habe mich die Letzten Tage dann mal mit einem Crobjob zu einer Beobachtung aufgemacht und habe festgestellt, dass dort folgendes zu sehen ist

  758     1 root     R N  13308  22%  74% ctlmgr
  654     6 root     SW<      0   0%  24% [capi_oslib]

Und laut RRDStats ist die Box ab 0Uhr für so 10min zu 100% ausgelastet und rebootet dann. Meine Push-Mail kommt aber jede nacht bei mir und und 5 min später gebootet die Box. Habe dann heut Tags über mal den Push-Service getestet mit dem gleichen Ergebnis.
Wollte den Push-Service dann deaktivieren um dies zu unterbinden. Einfach Haken raus und übernehmen, aber auch dabei ist die Last auf 100% gestiegen. Mit strace konnte ich geobachten, dass er sich an dieser Stelle aufhängt

poll(0, 0, 0)                           = 0 (Timeout)

Das macht die Box für eine lange Zeit, immmer immer wieder und sehr schnell, also bei hoher Last und wahrscheinlich bis der Watchdog einspringt...


Hat da jemand vielleicht ne Idee?

 

[RalfFriedl]

Wenn die Box diese polls in einer Endlosschleife durchführt, ist es kein Wunder, wenn dieser Prozeß so viel CPU-Last erzeugt. Ein poll mit 0,0,0 als Parametern hat keine sinnvolle Funktion, es gibt nichts, worauf gewartet werden sollte, und der Systemaufruf wartet auch nicht.
Bist Du sicher, daß sonst gar nichts passiert? Was passiert, bevor diese Sequenz anfängt?
Und oben ist ja auch Aktivität bei capi_oslib angezeigt, gibt es dafür einen Anlaß?

 

[hermann72pb]

Hast du vielleich SSL/TLS beim Push-Service aktiviert? Seit einigen Firmwares ist es seitens AVM -glaube ich- möglich. Wenn du da etwas mit SSL-Libs am Board hast, könnte es z.B. Probleme verursachen.

Entschuldigt die lange Antwortzeit.

Ich habe mehrere Sachen die SSL verwenden, habe aber seit mehreren Versionen jetzt schon alles statisch gebaut und ersetzte die libcrypto oder libssl nicht mehr. Auch habe ich im Push Service kein SSL eingtragen, weil das mal nicht lief, sondern mach das SSL an der Stelle per connect auf localhost und stunnel. Was auch soweit läuft.

Warum capi_oslib Last hat weiß ich nicht, ich habe alle Telefone direkt per Dect angeschlossen und nutzte ausschließlich Voip. Bei Push-Service lasse ich mir alles schicken.

Nachdem ich gestern den ctlmgr so oft am Tag gekillt und neugestartet habe wollte ich gestern abend nochmal nen kompletten strace machen, dort funktioniert dann komischer Weise das setzten der Einstellung (deaktivieren des Push-Service) und auch der Push-Service selber im Test und auch in der Nacht ohne Reboot der Box.

Heut morgen habe ich die Box dann rebootet um den Ausgangszustand wieder herzustellen und kann nun das gleiche Verhalten beobachten. Folgenden nun der Bereich des strace bevor die endlosen polls anfangen.

Jemand ne Idee?

 

[RalfFriedl]

Anscheinend wird da /lib/libmailbuilder.so nachgeladen, aber nicht in einem neuen Prozeß. Ich weiß nicht, ob es normal ist, daß danach noch die C-Library geladen wird, man sollte annehmen, daß der ctlmgr diese bereits geladen hat. Jedenfalls passiert nichts übermäßig auffälliges, bevor die poll-Aufrufe kommen.
Es wird auf die Existenz von /var/tmp/detail.html und /var/tmp/alt_detail.txt geprüft, ich weiß nicht, ob diese Dateien existieren sollten. Es wäre denkbar, daß das Problem daher kommt, auch wenn ich keine vernünftige Erklärung dafür hätte. Insbeondere fällt mir kein Grund ein, reguläre Dateien mit poll abzufragen.

Was passiert mit einer normalen AVM-Firmware? Und evtl. ein strace, wenn damit die Email versendet werden soll.
