推 swallowcc: 感謝@@> 我完全忽略開頭的#後面那些文字, 還以為那些是 04/14 08:17
→ swallowcc: 說明而已, 所以一直在爬中間那些看不懂的地方 orz 04/14 08:18
→ qrtt1: 緊張的時候，常看漏看東西的 04/14 09:08
→ qrtt1: 所以，你得研究是記憶體真的不夠，還是 memory leak 唄 04/14 09:18
※ 引述《swallowcc (罹患重度能年病的燕叔)》之銘言：
: 各位前輩好 ._.
: 最近管理的一台 tomcat 8 常常會噴 hs_err_pid.log 出來...
: 不過看著 log 內容有種不曉得該怎麼解析的無力感 orz
: 不曉得像這種 log 是否有專門的 analyzer 可以用？
: 還是有什麼眉角，可以從中就直接分析原因？
: （或者是有教學文件什麼的，讓我自己啃也OK @@）
: 感謝 <(_ _)>

# There is insufficient memory for the Java Runtime Environment to continue.
# Native memory allocation (mmap) failed to map 256901120 bytes for committing reserved memory.
# Possible reasons:
# The system is out of physical RAM or swap space
# In 32 bit mode, the process size limit was hit
# Possible solutions:
# Reduce memory load on the system
# Increase physical memory or swap space
# Check if swap backing store is full
# Use 64 bit Java on a 64 bit OS
# Decrease Java heap size (-Xmx/-Xms)
# Decrease number of Java threads
# Decrease Java thread stack sizes (-Xss)
# Set larger code cache with -XX:ReservedCodeCacheSize=
# This output file may be truncated or incomplete.

反正主因就是記憶體不足吧！
