Hi Everyone<br />
<br />
We are currently having an intermittent situation whereby our end users are sporadically being disconnected. &nbsp;We believe we have pinned it down to the MSExchangeRpcProxyFrontEnd<wbr />AppPool reaching its Private Bytes memory limit and then doing an automatic App Pool recycle and that this is then disconnecting our users. &nbsp;The Private Memory limit is set to about 1.5GB. &nbsp;Once it fills it forces an app recycle, kicking everyone connected to that process off. &nbsp;We see Event ID 5117 in system log followed by two events 5138, 5013. &nbsp;These appear to be IIS related<br />
<br />
Has anyone else encountered this issue, and if so how did you overcome it. &nbsp;Are we ok to increase that limit or even set it to 0 (unlimited) or are there any alternatives to resolve this and avoid disconnections.<br />
<br />
Thanks<br />
<br />

Exchange is the server side of a collaborative application product that is part of the Microsoft Server infrastructure. Exchange's major features include email, calendaring, contacts and tasks, support for mobile and web-based access to information, and support for data storage.

Exchange

Within Internet message handling services (MHS), a message transfer agent or mail transfer agent (MTA) or mail relay is software that transfers electronic mail messages from one computer to another using a client–server application architecture. A MTA implements both the client (sending) and server (receiving) portions of the Simple Mail Transfer Protocol (SMTP). The terms mail server, mail exchanger, and MX host may also refer to a computer performing the MTA function. The Domain Name System (DNS) associates a mail server to a domain with mail exchanger (MX) resource records containing the domain name of a host providing MTA services.

Email Servers

Microsoft Outlook is a personal information manager from Microsoft, available as a part of the Microsoft Office suite. Although often used mainly as an email application, it also includes a calendar, task manager, contact manager, note-taker, journal, and web browser.
