Diiwaanka "Qashin ururinta" ee JVM waxaa loo qaabeeyaa sida soo socota: 1aad. Khadkasta wuxuu matalaa hal howl oo qashinka la ururiyo oo ka bilaabanta waqtiga. 2aad. Cabirka ka hor iyo ka dib meelaha xusuusta ee kala duwan ee JVM waxaa lagu muujiyaa sida "MemoryArea: BeforeSize->AfterSize(AllocatedSize) " halkaas oo MemoryArea uu yahay mid ka mid ah PSYoungGen, ParOldGen, ama Metaspace.

1aad. Diiwaanka waxaa ku jira 47 howlgal oo GC ah muddo 36 daqiiqo ah laga bilaabo 7:00 AM ilaa 7:36 AM 30-ka Maarso 2023 UTC. 2aad. Hawlgalada GC waxay bilaabmaan qiyaastii hal daqiiqad waxayna qaataan wax ka yar shan ilbiriqsi midkiiba, laakiin 7:23 AM kadib, waxay si lama filaan ah u qaataan qiyaastii 30 ilbiriqsi midkiiba waxayna dhacaan laba jeer daqiiqaddii. In si kale loo dhigo, bilowga howlgallada GC waxay qaataan qayb yar oo ka mid ah waqtiga JVM, halka goor dambe, waxay qaataan ku dhowaad waqtigeeda oo dhan. Saddexaad. Hawlgallada GC ee muddadan labaad waxay keenaan hoos u dhac aad u yar oo ku yimaada tirada guud ee xusuusta iyo PSYoungGen, ParOldGen, iyo aagagga xusuusta Metaspace. Dhaqanka noocan ahi wuxuu si gaar ah u muuqdaa marka ay subaxdu tahay 7:26:51. 4. waxay Tani waxay muujineysaa in waqti badan lagu qaatay howlgallada GC-ga oo aan wax natiijo ah laga gaarin. 5aad. Tirada guud ee xasuusta markii hore si tartiib tartiib ah ayey uga kortaa 49.5 GB ilaa 52.3 GB, laakiin muddada labaad waxay ku egtahay qiyaastii 78 GB. Lix. Xasuusta loo qoondeeyey waxaa lagu go'aamiyaa 82 GB inta lagu jiro muddada labaad ee hawlgallada GC, taasoo muujineysa xadka dibadda. 7 (Toddobo) Waxaan kugula talinayaa inaad kordhiso xasuusta ugu badan ee loo qoondeeyay ee ka baxsan xadka 82 GB, laba jibaar haddii ay suurtagal tahay, oo dib u bilow JVM.
