Hi all, <br><br>Currently I am working on promotion failure about CMS, using the commanding line, -XX:+CMSDumpAtPromotionFailure -XX:+CMSPrintChunksInDump -XX:+CMSPrintObjectsInDump, below is gc log segment,<br><br>(0: promotion failure size = 10) (1: promotion failure size = 14)<br>
//question1, the size unit is bye or block?<br><br>0x039c0000: free block of size 16384:<br>Next: 0x00000000 Prev: 0x00000000 [can't coalesce]<br>//question2, what does this mean? Should I look into JVM source code to find the answer? if not, where to get references?<br>
<br>size bfrsurp surplus desired prvSwep bfrSwep count cBirths cDeaths sBirths sDeaths <br>//question3, can anyone explain these words? <br>
<br>thanks<br>
