パッチ名: PHCO_35996
パッチ摘要: 11.31 pthreadライブラリ累積パッチ
作成日: 07/03/01
公開日: 07/04/25
ハードウェアプラットフォームおよびOSリリース:
11.31
現象:
PHCO_35996:
(SR:8606473991 CR:JAGag28593)
たまに、同期オブジェクト上で待機しようとしているJavaアプリケーションで
コアダンプが取られることがあります。
問題点の説明:
PHCO_35996:
(SR:8606473991 CR:JAGag28593)
pthread_suspend()を使って、mutex、rwlockまたは条件変数のような同期オブ
ジェクト上で休眠しようしているスレッドを一時停止すると、問題が起きてい
ました。この場合に、libpthreadがそのスレッドに対応する内部データ構造を
更新していなかったため、再開時に、そのスレッドでSIGSEGVフォルトが起き
ていました。
解決方法:
データ構造を適切に更新するようにlibpthreadを修正しました。

JAGag28593: java applications may occasionally
dump core.
Category Tags:

Path Name: /hp-ux_patches/11.X/PHCO_35996
Symptoms:
PHCO_35996:
( SR:8606473991 CR:JAGag28593 )
Java applications may occasionally dump core while
trying to wait on a synchronization object.
Defect Description:
PHCO_35996:
( SR:8606473991 CR:JAGag28593 )
The problem happens when a thread which is about to sleep
on a synchronization object like mutex, rwlock or
condition variable is suspended using pthread_suspend().
In this window libpthread does not update the internal
data structures corresponding to the thread, resulting in
the thread faulting with SIGSEGV when it is resumed.
Resolution:
Now libpthread ensures that the data structures are updated
properly.
Enhancement:
No
