Selamlar,

Log dosyaları ile ilerlemek daha iyi bir sonuç verecek. " /var/log/messages " üzerinde hatalar ile ilgili bilgileri görebilirsiniz. Son kapanma zamanının 1 dakika öncesi ve sonrasını iletirseniz yorumlayabiliriz.

Merhaba,

Hangi sanal platformu kullanıyorsunuz? Sanal üzerinden loglara bakabilirsiniz sorunun kaynağı bir çok nedenden olabilir kullanılan linux versiyonu nedir?

Merhaba lütfen yazmam gereken tam komutu verebilir misiniz ?

Oracle linux kullanıyorum / vm üzerinde çalışıyor.

Aldığım hata mesajı aşağıda ki gibidir.

[root@server ~]# /var/log/messages
-bash: /var/log/messages: Permission denied

root kullanıcısı ile 

tail -10 /var/log/messages , komutu verirsen log dosyanın son 10 satırını okuyabilirsin.  Rakamı dilediğin gibi arttırman mümkün. Buradan hata mesajlarını okuman gerekecek.

Merhaba,

Log dosyalarının bu sabaha ait olanlarını aldım.
Çok uzun olduğu için ekli foruma EK olarak metin belgesinde yükledim.  Lütfen inceleyebilir misiniz.

Merhaba,

Linux konusunda uzman olan hocalarımız daha detaylı size bilgi verebilir ancak loglarla baktığımda,

Jan 25 07:49:18 erpserver automount[2049]: problem reading master map, maximum wait exceeded
Jan 25 07:49:18 erpserver automount[2049]: automount: warning: could not read at least one map source after waiting, continuing ...

Bu hata üzerinde yoğunlaşabillirsiniz google üzerinden bazı dökümanlar mevcut inceleyebilirsiniz.

Bu uyarıdan sonra sanırım linux kapanıyor saatlere dikkat ederseniz.

merhaba,

kullandığınız hypervisor nedir ?

ilgili vm üzerinde düzenli olarak kaynak tüketimini takip ediyor musunuz ?

cron jobları incelediniz mi ?

son olarak hypervisor guest tool yüklü mü ?

Merhaba,

Bize makina restart olduğu anki raporları gönderirsen daha iyi olacak. Buradan birşey çıkartamadım.

Selam sisteminizde çok fazla bellek uyarısı var 

Jan 25 07:49:18 erpserver automount[2049]: problem reading master map, maximum wait exceeded

sistem kendini korumaya almak için resetliyor

ya ramlarda sorun var yada kapasitesi yetersiz öncelikler ram kapasitenizi arttırın devam ederse ram fiziksel olarak gözden geçirin

Merhaba,

Host 'da  3 PC daha var.
Tek linux makina bu.   64gb ram i var.   Eğer ram ile ilgili bir sıkıntı var ise bunu host üzerinden kontrol edebilir miyim ?

Makinanın restart problemi devam ediyor.

Restart problemim devam ediyor.

Selamlar,

Gönderdiğiniz log içinde aşağıdaki uyarılar dikkatimi çekti. Bu uyarının anlamı guest(vm) için ayırdığınız ram yetmiyor ve balloon oluşuyor. ilgili guest ( vm ) için ram miktarını arttırıp vmtools yükleyip monitör edebilir misiniz? Hatta bu makina için kaynakları allocate edin. ilgili guest sağ tuş edit settings-resources - memory - reservation ( 65GB veya daha yukarısı için sabitleyin)

Güray bey merhaba,

Memory ekran görüntüm aşağıda ki gibidir,  (#1)
Bir sonraki görüntü ise eğer sizi doğru anladıysam önerdiğiniz değişiklikler  sizi doğru anladıysam lütfen onaylayabilir misiniz.

Selam

Tavsiyem linux sistemine webmin kurman ve onun üzerinden monitörize etmen daha kolay olacaktır 

memory ekran görüntüm aşağıda ki gibidir,  (#1)
Bir sonraki görüntü ise eğer sizi doğru anladıysam önerdiğiniz değişiklikler  sizi doğru anladıysam lütfen onaylayabilir misiniz.

reverse all guest memory ( all locked ) seçeneğini aktif etmeniz, doğru olan adım.

os seviyesinde monitoring yapmanızı öneririm, bu konuda referans adres fikir verecektir.
